PROCESS OF PRODUCING TRANSFERS.

SPECIFICATION forming part of Letters Patent No. 663,539, dated December11, 1900.

Application filed June 1, 1900- Serial No. 18,688 (No specimens.)

T0 whom it may concern.-

Be it known that I, CARL GIEsncKE, a citizen of Germany, and a residentof Hanover, Germany,have invented certain new and useful Improvements inProcesses of Producing Transfers, of which the following is aspecification.

Heretofore when type Writers were employed for making transfers it wasnecessary to transfer the writing to be multiplied upon anespecially-prepared transfer-paper. The use of this paper isobjectionable in that the original writing, owing to its greatsensibility, will only permit a clean and unobjectionable transfer underexceedingly careful and skilled manipulation. Generally the use of thispaper, which is prepared on but one side and is thus apt to coil, woulddamage, oblit' erate, or blot the writing, and the latter could becorrected either not at all or at least with great difficulty.

To remove the above objections in transferring, I have devised improvedmeans to render the use of especially-prepared paper entirelyunnecessary, so that any ordinary paper may be employed for thereception and transfer of the original writing.

In carrying my invention into effect I employ a compound which containsthe ingredients necessary for the transfers at such a concentration thatafter their transfer upon a ribbon, sheet, pad, 850., a ready and cleantransfer to ordinary paper may be accomplished either by causing thetype-writer or other type to act upon the body carrying the compound orby transferring sheets, as with the usual transferring-machines.

If the color-ribbon of a type-writer is prepared on one of its sideswith the compound employed by me, the ribbon will upon being struck uponits back by the type transfer the copying substance in such a mannerupon ordinary paper that such paper may be used directly fortransferring the writing to a stone or zinc plate.

The copying substance on the ribbon is so constituted that it willtransfer only at the points struck by the type, while it will not adhereto those parts which are to remain clean. The same applies to sheetsprepared with the copying substance and which are used for transferringpurposes.

If desired, suitable pads may be prepared with the copying substancewhen the type, which is brought into direct contact with the pad, willtake up the substance and give it off subsequently upon striking thepaper. Pads thus prepared may, for example, be used with the Yosttype-writer.

The copying substance employed in carrying my invention into effect iscomposed, essentially, of the following ingredients: first, lithographicink in a dissolved or ground state; second, transfer-ink. To these twoprincipal ingredients the following are added: turpentine and printersvarnish to dissolve and dilute, oil to obtain the necessary fattymatter, and, if desired, some spirits of ammonia to accelerate thedrying and smoothing.

To prepare the compound, I proceed as follows: In a porcelain mortar Igrind one-half gram of the best transfer-ink with one gram of varnishand turpentine until completely dissolved. I then add about two grams ofoil of lavender and under continued grinding I add gradually about fiveto ten grams of lithographic ink, which when in a solid state and thencalled transfer stick-touche,

has previously been dissolved in distilled water. To accelerate thedrying, especially in warmer seasons, some drops of spirits of ammoniamay be added. The lithographic ink is of the kind used for multiplyingoriginals. The essential ingredients of this ink are frequently embodiedinto solid sticks, which are preferred on account of their purity andwhich are dissolved and ground before use.

The copying substance is uniformly spread in a liquid or pasty conditionupon ribbons, sheets, or pads. The body of the ribbon or sheet ispreferably composed of thin, very durable, and closely-Woven linen,while the pads may be composed of fine felt or similar material. After asingle or several uniform applications (during which a glass plate maybe used as a foundation) the ribbons, sheets, or pads are allowed to dryand are then ready to be used in the manner described. In warm seasonsthe ribbons coiled up in the type-writer may be dusted over withpotatoflour starch to prevent pasting together.

The writing obtained by means of the abovedescribed transfer substanceupon the ordinary preferably well-glazed paper may be used at leastthree or four times for transfers upon stone or zinc plates.

The advantages of my improved process are, briefly, as follows: Ordinarypaper possesses suflicieut resistance and insensibility. The

original writing upon it does not become extinguished or blurred and maybe corrected without ditficulty. Evenan unskilled person can with theribbons, sheets, or pads prepared in the manner described make anabsolutely clean and perfect transfer. The process is furthermore muchcheaper, not only because the prepared paper is dispensed with and thepreparation of the ribbons, sheets, and pads is very simple, but alsobecause by the direct 19th day of May, 1900 Y CARL GTESECKE.
